pbiviz doesn't work

Hi everyone.

I have a pbiviz version of 2.3 installed, and recently, I got following problem. When I type "pbiviz" or any other pbiviz command in command line, I get following message:

Node Commands

Syntax:
    node {operator} [options] [arguments]

Parameters:
        /? or /help   - Display this help message.
        list          - List nodes or node history or the cluster
        listcores     - List cores on the cluster
        view          - View properties of a node
        online        - Set nodes or node to online state
        offline       - Set one or more nodes to the offline state

I tried reinstalling pbiviz, different version and starting command prompt as admin, still get same error. What can be source of error?
